662
The 662 Pump Up Control provides reliable liquid level management for industrial applications. Its automatic reset function and two adjustable trip points ensure precise control over fluid levels. Operating on 24VDC with a 4-20mA input signal, this unit integrates seamlessly into existing control systems. The robust design accommodates operating temperatures from -13° to +122° F and humidity up to 97% without condensation, ensuring consistent performance in demanding environments. With a mechanical relay life of 10 million operations, the control offers extended operational longevity, reducing maintenance frequency. Its compact ABS plastic enclosure and 11-pin socket mounting facilitate straightforward installation and maintenance procedures. Integrated PUMP UP and INPUT LOOP ERROR LEDs provide immediate operational status feedback, enhancing system diagnostics and uptime for critical processes.
The Model 662 Pump Up Control, part of the 600 series line of
instrumentation controls, is designed to monitor andmaintain liquid
levels. A user-provided 4-20mA current loop represents the liquid level,
and output connections are provided for pump control. The HIGH
ADJUSTsetpoint, and the LOW ADJUST setpoint, are field adjustable. If
the input falls below the low setpoint, the PUMP UP relay energizes, and
remains that way until the input rises above the high setpoint. The high
setpoint must always be set above the low setpoint. Top-mounted LEDs on
the Model 662 show system status. The PUMP UP LED turns ON when the
input falls to 10% below the low setpoint, and resets when the input
rises above this level. An INPUT LOOP ERROR LED turns ON if the input is
outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or
equivalent) is required to provide the 24 VDC operating voltage. A Time
Mark Model 672-15 Pressure Transducer (or equivalent) is required to
provide the input signal.
